    /**
     * @fileoverview
     * some functions for browser-side pretty printing of code contained in html.
     *
     * <p>
     * For a fairly comprehensive set of languages see the
     * <a href="http://google-code-prettify.googlecode.com/svn/trunk/README.html#langs">README</a>
     * file that came with this source.  At a minimum, the lexer should work on a
     * number of languages including C and friends, Java, Python, Bash, SQL, HTML,
     * XML, CSS, Javascript, and Makefiles.  It works passably on Ruby, PHP and Awk
     * and a subset of Perl, but, because of commenting conventions, doesn't work on
     * Smalltalk, Lisp-like, or CAML-like languages without an explicit lang class.
     * <p>
     * Usage: <ol>
     * <li> include this source file in an html page via
     *   {@code <script type="text/javascript" src="/path/to/prettify.js"></script>}
     * <li> define style rules.  See the example page for examples.
     * <li> mark the {@code <pre>} and {@code <code>} tags in your source with
     *    {@code class=prettyprint.}
     *    You can also use the (html deprecated) {@code <xmp>} tag, but the pretty
     *    printer needs to do more substantial DOM manipulations to support that, so
     *    some css styles may not be preserved.
     * </ol>
     * That's it.  I wanted to keep the API as simple as possible, so there's no
     * need to specify which language the code is in, but if you wish, you can add
     * another class to the {@code <pre>} or {@code <code>} element to specify the
     * language, as in {@code <pre class="prettyprint lang-java">}.  Any class that
     * starts with "lang-" followed by a file extension, specifies the file type.
     * See the "lang-*.js" files in this directory for code that implements
     * per-language file handlers.
     * <p>
     * Change log:<br>

        * where index_n is an index into the sourceCode, and style_n is a style
        * constant like PR_PLAIN.  index_n-1 <= index_n, and style_n-1 applies to
        * all characters in sourceCode[index_n-1:index_n].
        *
        * The stylePatterns is a list whose elements have the form
        * [style : string, pattern : RegExp, DEPRECATED, shortcut : string].
        *
        * Style is a style constant like PR_PLAIN, or can be a string of the
        * form 'lang-FOO', where FOO is a language extension describing the
        * language of the portion of the token in $1 after pattern executes.
        * E.g., if style is 'lang-lisp', and group 1 contains the text
        * '(hello (world))', then that portion of the token will be passed to the
        * registered lisp handler for formatting.
        * The text before and after group 1 will be restyled using this decorator
        * so decorators should take care that this doesn't result in infinite
        * recursion.  For example, the HTML lexer rule for SCRIPT elements looks
        * something like ['lang-js', /<[s]cript>(.+?)<\/script>/].  This may match
        * '<script>foo()<\/script>', which would cause the current decorator to
        * be called with '<script>' which would not match the same rule since
        * group 1 must not be empty, so it would be instead styled as PR_TAG by
        * the generic tag rule.  The handler registered for the 'js' extension would
        * then be called with 'foo()', and finally, the current decorator would
        * be called with '<\/script>' which would not match the original rule and
        * so the generic tag rule would identify it as a tag.
        *
        * Pattern must only match prefixes, and if it matches a prefix, then that
        * match is considered a token with the same style.
        *
        * Context is applied to the last non-whitespace, non-comment token
        * recognized.
        *
        * Shortcut is an optional string of characters, any of which, if the first
        * character, gurantee that this pattern and only this pattern matches.
        *
        * @param {Array} shortcutStylePatterns patterns that always start with
        *   a known character.  Must have a shortcut string.
        * @param {Array} fallthroughStylePatterns patterns that will be tried in
        *   order if the shortcut ones fail.  May have shortcuts.
        *

        *   function that takes source code and returns a list of decorations.
